Concrete mix for exposed exterior slab on grade:

Concrete mix for exposed exterior slab on grade:

Party pavilion, open 4 sides, wood trusses on columns at roof. Location in IL (frost and snow). My question is about my slab on grade mix design. I have the following:

Min f'c = 3000 psi.
Min cement. Material = 520 lb/cubic yd.
Max W/C = 0.40
Slupm = 4" + - 1"
Air content = 5.5% + - 1

This is the typical SOG design we use for interior slabs. Should I change anything for the exterior use?

Sorry wrong forum. I'll be re-posting this in the "other topics" forum. Delete this one if you like.
